Natsuo Ishidou is so amazingly awesome it's a burden. She can beat anyone in any sport, effortlessly, but in doing so drives everyone away, and so she is desperately lonely.

Actually she's just a [[JerkAss sadistic bitch]] of a high-school girl. When she finally meets someone, Yuzuko Mawatari, who's much better at her in a sport she can't effortlessly excel at, MixedMartialArts, ''and'' who is happy and well-balanced, she makes it her mission in life to ''[[TallPoppySyndrome run Yuzuko into the ground.]]''

A {{Seinen}} {{manga}} series written by Oota Moare, serialized in a small magazine ''Good! Afternoon.'' It ran for 32 chapters from 2008 to 2015. It has a lot in common with ''Manga/{{Airmaster}}'', which also features a tall schoolgirl who excels at sports as the main character and largely avoids fanservice, although [[Manga/{{Airmaster}} Maki]] is much less a sadistic bitch and more a ShrinkingViolet. Also, ''Teppu'' is very realistic, while ''Airmaster''... isn't.

Teppu can be best thought of as an inverted {{Shounen}} manga. Natsuo, instead of being a happy and well-balanced young male, is an easily irritated and arrogant young female. Instead of starting off relatively weak and working her way up, Natsuo is already one of the best; Yuzuko is her first real challenge in ages. Instead of losing her first fight and learning some lesson about hard work, she wins it handily, through a cheap tactic. Really, Natsuo acts as an [[VillainProtagonist antagonist]] to Yuzuko, having all the characteristics TheRival would have in a regular Shounen work. The best part is that this is all lampshaded by various characters, often Natsuo, who sees the whole situation as irritating, though also accepts being a VillainProtagonist rather easily.

------!!This series provides examples of:* [[AbusiveParents Abusive Brother]]: The explanation for why Natsuo acts the way she does. May have something to do with how she, the younger sister, saved her brother from bullying in middle school. Might have also turned him into a shut-in. All we know that she's ''terrified'' of him.* TheAce: Yuzuko and Ringi. Natsuo qualifies for most of the sports she tries but not MMA, to her relief.* ActionGirl: Most characters. Natsuo, Yuzuko, Sanae, Ringi, Karin, and Haruka all qualify. It's a mostly realistic manga about women in MMA, what do you expect? In fact, there are pretty much only two named male fighters, Mario and Risuke. Both are, story-wise, defined in terms of the female characters, and in Risuke's first appearance he gets beat by Ringi in a [[spoiler:staged]] fight.* ALessonInDefeat: Natuso invokes this on herself. Her second meeting with Yuzuko has her challenging her to a spar knowing full well she's going to lose to try and understand her growing interest in MMA. Haruka also notes in training that Natsuo frequently ''allows'' herself to be taken by attacks to learn how to deal with them and she was more excited at the prospect of losing her first tournament than winning.* AmbiguouslyGay: Mai.* AwesomenessByAnalysis: To an extent, Natsuo, who after realizing she can't just bull through MMA like with everything else, spends the time to carefully examine the holds and locks, often deliberately allowing herself to be caught by the opponent.* [[spoiler:TheBadGuyWins]]: Well, more like [[spoiler:The Good Guy Wins since Natsuo is basically the {{villain|Protagonist}} of the story.]]* BigOlEyebrows: Yuzuko's most notable feature, besides her (short) height. To the point where they're referenced in the titles of ''nine chapters''.* BittersweetEnding: [[spoiler: Natsuo is defeated by Yuzuko during the final round of the tournament, making all of her hard work for nothing. Still, she considers it something of a moral victory, and she is able to tell Yuzuko that they're nothing alike. Though Yuzuko's MMA career continues to take off thanks to her tournament victory, Natsuo makes it clear that she still intends to one day defeat her and those like her]].* BlandNameProduct: [[http://mangafox.me/manga/teppuu/v01/c004/10.html Googlu]]* BloodKnight: Natsuo, full stop. She's only ever happy when challenged in some sport. Too bad she's too good at them all.** She softly smiles with a LuminescentBlush... at the thought of fighting in the G-Girl tournament.** She gets depressed after her first MMA bout win against someone with years on her in experience... Because, as the underdog, she was hoping she'd get trounced by someone genuinely stronger than her.* BossInMookClothing: Park Du-na doesn't seem like much at first glance, but she's actually the favorite to win the G-Girl preliminary tournament. [[spoiler:Yuzuko struggles against her for most of their fight before finally getting her in a Guillotine Choke.]]* CaptainErsatz: Shinobu Kannagi is pretty blatantly based off of female judoka and pro wrestler Shinobu Kandori.* CatFight: Averted. MMA involves a lot of grappling and holds, and the style remains semi-realistic (this sometimes leads to complaints about feeling detached).* CatGirl: Fellow Takenaka Gym member Manami Hiki is about as close to one as you can get in a fairly realistic manga. All she's really missing are ears and a tail.** In a Bonus Chapter after Chapter 26, Manami actually does sport some cat ears, as a [[spoiler:punishment when she, Natsuo, and Haruka lose a game of dodgeball]], [[http://www.mangahere.co/manga/teppuu/c026.5/12.html but she doesn't seem to mind at all.]]* CurbStompBattle: [[spoiler:Natsuo vs. Hisako Sogabe in the first round of the G-Girl tournament. A good chunk of the chapter is spent talking up Hisako's strength, stamina, and the fact that she's a ''very'' dangerous opponent. Natsuo knees her in the face and wins the fight within seconds of the match starting.]]** [[spoiler:Curbstomp Battles seem to be the name of the game with G-Girl. Sanae and a new character, Park Doona, win their first fights incredibly easily as well. In-universe the number of quick knock outs is treated as incredibly surprising.]]* CutShort: The manga ends directly after the G-girl qualifiers, apparently due to illness on the author's part.* {{Deconstruction}}:** Yuzuko is a deconstruction of the typical sports manga protagonist. Spirited, hard-working, not afraid of anything, incredibly determined, enjoying the sport no matter what happens...and everyone around her finds it to be creepy, to an almost uncanny valley degree. A normal person should be nervous, should be afraid at points, should be excited when they win and sad when they lose, not just have a permanent smile stuck on their face. Most of her opponents interpret her high spirits and love of the sport as her mocking them when she wins. All of that just drives most people away from her. Yuzuko herself just doesn't get what's wrong, and why everyone isn't having fun like she is.** In the ending [[spoiler:Natsuo is defeated, but unlike in other manga where DefeatEqualsFriendship, she doesn't connect with Yuzuko: she rebukes Yuzuko's offer of friendship and tells her they're nothing alike.]]* DoesThisRemindYouOfAnything: One early scene has Natsuo fantasizing about finally beating Yuzuko. Her victory expression (which she makes while straddling a defeated Yuzuko) is...[[http://i.imgur.com/bM5ZtT8.jpg odd, to say the least]].* DownerEnding: It depends on your point of view. [[spoiler:It is perfectly in line with the tone and premise of the overall series, but the fact that Natsuo seemingly learned absolutely nothing from her loss could still be seen as this]].* FreudianExcuse: As mentioned above, it's heavily implied that Natsuo's cold, violent behavior is at least partially due to abuse from her brother and the bullying she was subjected to as a child.* GenkiGirl: Yuzuko. It's part of why Natsuo dislikes her so much. Also Ringi.* HardWorkHardlyWorks: Averting this trope is the foundation of the story: Natsuo has the ability to excel at any of the sports offered by her high school without even trying. MMA is the first sport she's encountered she actually has to work at, and despite having TheGift she's still a small fry with lots of hard work and disappointment ahead of her if she wants to excel at it. And she loves it.** Yuzuko averts this as well, being the classical underdog who started out with little talent but working herself to the bone to get good at MMA -- and it has worked out for her just fine so far.* HopeSpot: In the final chapter, it seems like Natuso may have finally repaired her relationship with her brother as they sit together and watch a movie. [[spoiler: It turns out it was AllJustADream]].* HugeSchoolgirl: Natsuo, at 6'. She secretly longs to be shorter, as shown in a dream sequence in chapter 27.** Haruka Kirido as well who's only a few centimeters shorter than Natsuo.* InelegantBlubbering: [[spoiler:[[https://40.media.tumblr.com/f0ce5ba9925dc99db2e5059a2701ae66/tumblr_inline_nr99pnNVdU1r31abn_540.png Oh yeah.]]]]* InvincibleHero: Natsuo has lost twice, both times against Yuzuko, and fully expected to the second time, though she didn't anticipate how badly she was going to get beaten. Her first "real" fight was won easily, and she kicks everyone's ass at anything that isn't MMA. All of this greatly disappoints her. [[spoiler:She loses in the finale as well, though she considers it a sort of moral victory in being able to give voice to her loathing. Seeing it averted may or may also not have helped fix things with her brother.]]* JerkAss: Natsuo is very up front about it, too. Oh, and also Karin, Natsuo's teacher, though it manifests somewhat differently.** And Mario Cordeiro, though it's uncertain how much of it is putting on a show to promote interest in women's MMA, and how much of it is genuine contempt towards Risuke Takenaka.*** Given how he brought over a fighter from America solely to act as a sparring partner/punching bag for Yuzuko and Ringi without telling her that's why he brought her over... yeah Mario's kind of a jerk.* LampshadeHanging: Natsuo occasionally references standard manga tropes and how she's avoiding them.* MartialArtsDoNotWorkThatWay: Averted big-time. In terms of the niche, one of the most realistic ones around.* MoralityPet: To an extent, Kei for Natsuo, who appears to be Natsuo's only friend.* NoPeriodsPeriod: Nope: Karin advises Natsuo and the other girls in her gym to rest during their period.* PerpetualFrowner: Natsuo's default expression is a frown. Smiles are reserved for insults or anticipation of a challenge.* SchoolgirlLesbians: It's heavily implied that Sanae's friend Mai is in love with her. At one point Mr. Kanno flat out says this is the case, causing Mai to blush and claim that it's not what it looks like.* SlasherSmile: A really good one develops at the end of chapter 3, when Natsuo resolves to beat Yuzuko down with "all of her effort." Not to mention her glee at the end of chapter 10.* TrainingFromHell: Punishing (yet realistic!) levels of physical training are what make Yuzuko and Ringi such good fighters, and Natsuo, while considered by many to be pretty strong, is told point-blank by Karin that she'll need to go through a lot more conditioning if she ever intends to seriously participate in MMA.* UnskilledButStrong: Natsuo has a great deal of natural athletic talent, but when facing fighters on a significantly higher level like Yuzuko she comes up short due to her lack of formal training and conditioning.* VillainProtagonist: As said before, in a normal Shounen manga, Natsuo would be the antagonist for Yuzuko.----
